F# maj also works for the second chord in the :library loop, but I think the original adds the 9th (or else, I just prefer it in there)

Note the ##| comments are to toggle lines with Cmd/Ctl-/ and turn the :takeout loop off. When you stop that loop, you then need to sync at the beginning instead of at the end, else when you restart it, it'll be out of phase with the chords in :library
